+Subject: [PATCH 14/15] LT pthread_atfork: unhide
+
+Trying to compile perl with uClibc new linuxthreads on arm.
+I run into the problem that pthread_atfork is not available.
+The problem was that it was synced with the glibc version, which has
+compat ifdefs we do not need in uClibc. The inital checked in version
+is right and works. So either revert the commit 2 years ago
+or patch it with the patch attached I made for openembedded.

+Subject: [PATCH 02/15] avr32: add varargs handling of prctl syscall
+
+prctl is defined to use varargs in the header file, hence it needs varargs
+specific handling in the source. This patch properly handles the variodic
+argument before the syscall is passed to the kernel for the AVR32 architecture.

+Subject: [PATCH 07/15] fstatat: fix up behavior on 32/64 bit hosts
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The fstatat() syscall is a little funky in that it sometimes changes name
+between 32 and 64 bit hosts, but it should always operate on a 64bit stat
+structure.  So for the fstatat() function, make sure we convert it from a
+64bit kstat to a 32bit stat.
+
+Along these lines, we need to restore the __xstat32_conv() function.

+Thanks, indeed.  If we came into "#elif WORDSIZE == 32" block, above
+condition never be true.  So we can just move this statement out of
+"#if...#elif...#elif...#endif" block.  Here is a revised patch.
+
+------------------------------------------------------
+From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
+Subject: [PATCH] getdents: Fix mips64 build
+
+Some archs (such as mips64) do not have getdents64 syscall but have
+getdents syscall.  Define alias for it.
+
+This fixes regression from 0.9.30.1.
+
+Backgrounds:
+This is once done by commit e8b1c674.  But after the commit 33bcf733
+("Use getdents syscall if kernel provide supports for this instead of
+relying upon getdents64."), if __ASSUME_GETDENTS32_D_TYPE was defined
+the alias for getdents64 is not defined.  The macro
+__ASSUME_GETDENTS32_D_TYPE had been effectively ignored until 0.9.30.1
+but the commit 0f0f20ab ("Move kernel-features.h header from the
+linuxthread directory to a common one...") really enables it.

+Subject: [PATCH 09/15] malloc: fix race condition and other bugs in the no-mmu malloc
+
+Fixes multiple race conditions on mmb list. This was done by
+making the mmb_heap_lock into a recursive lock and making the
+regular heap_lock extend to cover the mmb heap handling.
+
+Also move the new_mmb allocation up to before the mmb list is
+iterated through to find the insertion point. When the mmb_heap
+also runs out and needs to be extended when the regular heap is
+just extended, the mmb list could be messed up.
